Speak to your servicing dealer when you select your chain oil. Note: This product has an automatic chain lubrication system. You can also adjust the oil flow. Refer to To adjust the chain oil flow on page 30.
• Will the chain brake always protect me from injury during a kickback? No. The chain brake must operate correctly to give protection. The chain brake must also be engaged during a kickback to stop the saw chain. If you are near the guide bar, it is possible that the chain brake does not have time to stop the saw chain before it hits you. To prepare start with a warm engine WARNING: The chain brake must be engaged when the product is started to decrease the risk of injury. 1.
WARNING: Do not twist the starter rope around your hand. To stop the product 1. Push the start/stop switch down to stop the engine. 5. Pull the starter rope handle quickly and with force. Pull stroke and push stroke You can cut through wood with the product in 2 different positions. • To cut on the pull stroke is when you cut with the bottom of the guide bar. The saw chain pulls through the tree when you cut. In this position you have better control of the product and the position of the kickback zone.
2. Cut approximately ⅔ through the trunk and then stop. Turn the trunk and cut from the opposite side. 1. To use the cutting technique WARNING: Use full throttle when you cut and decrease to idle speed after each cut. 2. To cut a trunk that has support on one end WARNING: Make sure that the trunk does not break during cutting. Obey the instructions below. CAUTION: Engine damage can occur if the engine runs for too long at full throttle without load. 1. Put the trunk on a saw horse or runners. 1.
2. Cut through the remaining part of the trunk on the push stroke to complete the cut. b) Select the applicable cutting technique for the tension in the branch. 1. 2. WARNING: Stop the engine if the saw chain gets caught in the trunk. Use a lever to open up the kerf and remove the product. Do not try to pull the product out by hand. This can result in injury when the product suddenly breaks free. To use the limbing technique Note: For thick branches, use the cutting technique.
a) Select the applicable cutting technique for the tension in the branch. 2. Make sure that no person is in the risk zone before or during felling. To calculate the felling direction WARNING: If you are not sure about how to cut the branch, speak to a professional chainsaw operator before you continue. Refer to To cut trees and branches that are in tension on page 20 for instructions on how to cut branches that are in tension.
complete. It is important that you hear sounds and warning signals. The felling hinge To clear the trunk and prepare your path of retreat The most important procedure during tree felling is to make the correct felling hinge. With a correct felling hinge, you control the felling direction and make sure that the felling procedure is safe. Cut off all branches from your shoulder height and down. The thickness of the felling hinge must be equal and a minimum of 10% of the tree diameter. 1.
To use the safe corner method The felling cut must be made slightly above the directional cut. WARNING: Be careful when you cut with the guide bar tip. Start to cut with the lower section of the guide bar tip as you make a bore cut into the trunk. b) Cut on the pull stroke through the remaining trunk. c) Cut straight into the trunk from the other side of the tree to complete the felling hinge. d) Cut on the push stroke, until ⅓ of the trunk is left, to complete the safe corner. 3.
5. Make one or more cuts of sufficient depth necessary to decrease the tension. Cut at or near the point of maximum tension. Make the tree or branch break at the point of maximum tension. The safest procedure is to use one of the following winches: • Tractor-mounted WARNING: Do not cut straight through a tree or branch that is in tension. WARNING: Be very careful when you cut a tree that is in tension. There is a risk that the tree moves quickly before or after you cut it.
